[BUG] Personal Pro/Max subscription blocked with "organization has disabled Claude subscription access" error

Preflight Checklist

What's Wrong?

I have a personal Claude subscription (not part of any Team or Enterprise organization) and cannot use Claude Code with my subscription login. Every request is blocked with:

"Your organization has disabled Claude subscription access for Claude Code · Use an Anthropic API key instead, or ask your admin to enable access"

I have no ANTHROPIC_API_KEY set in my environment, and I never intentionally created or joined any organization. This appears to be tied to an auto-generated personal organization that is incorrectly flagged as having subscription access disabled.

What Should Happen?

Claude Code should authenticate successfully using my active, paid personal subscription login, without requiring an API key and without showing any "organization disabled" error, since I am an individual subscriber and not part of any Team/Enterprise org with admin-controlled restrictions.

Error Messages/Logs

Your organization has disabled Claude subscription access for Claude Code · Use an Anthropic API key instead, or ask your admin to enable access

Steps to Reproduce

1. Launch Claude Code (claude)
2. Log in using "Claude account with subscription" (Pro/Max)
3. Confirm no ANTHROPIC_API_KEY is set (echo $ANTHROPIC_API_KEY returns empty)
4. Run /status — shows Auth method: Claude AI (not API key), Plan: [你的计划], Organization: [auto-generated personal org]
5. Send any prompt to Claude Code
6. Error appears: "Your organization has disabled Claude subscription access for Claude Code..."

Is this a regression?

No, this never worked

Claude Code Version

Notably, even claude --version — which should not require any authentication — is blocked by this same error, suggesting the organization check runs before any command execution rather than being scoped to actual API requests.
